If you want to go cheap then just look for a suitable bolt on FleaBay - saves petrol/Gas!

Make sure you order a bolt that will protrude about 7/8 mm above the Top Plate and this should fit pretty much any head. Some heads will allow more - for example my Wimberley 2 allowed me to replace the 3/8 stud on one of my Gitzo Top Plates with one that has 18 mm of contact (11 mm more thread contact) that head is NOT shifting!

Choderboy wrote in post #18448353Is it just a bolt? A Gitzo has a custom part, 3/8 thread protrudes as in your photo but below the plate it is a much larger threaded section that fits into the flat plate.

I just made a spacer for my tripod which required a 3/8 thread to mount a head. I checked my ball head and there is 27mm inside so I made it about 20mm of thread protruding

The "conversion" that I did was on a Gitzo Systematic Top Plate, so it's a very similar situation to the OP's Feisol. Were they normal tripods (with center columns) then just using a bolt would not work.

It appears (on friend's 3342 and 3442 Feisols) to just be a simple 3/8 thread through the plate. As the OP has the top plate without anything in the middle it will be very easy for them to confirm this.

" I checked my ball head and there is 27mm inside" WOW! I didn't realise that any ball head allowed that much thread contact area - I don't think your ball head is going anywhere in a hurry!
